Question

How do you solve for c in `5p + 9c = P`?

Answer 1

`c = 1/9 (P - 5p)`

Explanation:

Isolate the term with c on the left side. This involves subtracting 5p from both sides.

hence : 5p + 9c - 5p = P - 5p → 9c = P - 5p

now divide both sides by 9

`(cancel(9)c)/cancel(9) = (P - 5p )/9 " or " 1/9(P - 5p )`
